A method of designing a series of waveforms for current cycles generated by a waveform generator to control the waveforms of a welding process performed by an electric arc welder, where the waveforms are stored in a memory stack by work points. The method comprises: integrating the arc current of the waveform designed for each of the many work points to obtain an integrated amount; plotting the integrated amounts for each of the work points; creating a regression curve statistically matching the plotted amounts to reveal outlier amounts; selecting an outlier amount; and, changing the waveform corresponding to the selected outlier amount to decrease the deviation of the integrated amount of the changed waveform from the regression curve.

A method of designing a series of waveforms for current cycles generated by a waveform generator to control the waveforms of a welding process performed by an electric arc welder, said waveforms being stored in a memory stack by work points, said method comprising:
A method of designing a series of waveforms for current cycles generated by a waveform generator at the output of an electric arc welder for a number of work points, such as wire feed speeds, said method comprising integrating the arc current of a waveform designed for each of said work points, plotting said integration amounts per work point identifying any of said integration amounts deviating from a curve statistically matching said amounts and manually changing said waveform corresponding to said deviated amount to smooth said series of waveforms.
